validation: Test task modes
The test source code is generated from specification items
by the "./spec2modules.py" script contained in the
git://git.rtems.org/rtems-central.git Git repository.
Please read the "How-To" section in the "Software Requirements Engineering"
chapter of the RTEMS Software Engineering manual to get more information about
the process.

+ *
+ * @brief Tests the task mode constants and function-like macros of the Classic
+ * API.
+ *
+ * This test case performs the following actions:
+ *
+ * - Validate the non-default task mode constants.
+ *
+ * - Check that RTEMS_NO_ASR is a power of two representable as an integer of
+ * type rtems_mode.
+ *
+ * - Check that RTEMS_NO_PREEMPT is a power of two representable as an
+ * integer of type rtems_mode.
+ *
+ * - Check that RTEMS_TIMESLICE is a power of two representable as an integer
+ * of type rtems_mode.
+ *
+ * - Validate the default task mode constants.
+ *
+ * - Check that RTEMS_ASR is equal to zero.
+ *
+ * - Check that RTEMS_DEFAULT_MODES is equal to zero.
+ *
+ * - Check that RTEMS_NO_TIMESLICE is equal to zero.
+ *
+ * - Check that RTEMS_PREEMPT is equal to zero.
+ *
+ * - Validate RTEMS_ALL_MODE_MASKS.
+ *
+ * - Check that the bitwise and of RTEMS_ASR_MASK and RTEMS_ALL_MODE_MASKS is
+ * equal to RTEMS_ASR_MASK.
+ *
+ * - Check that the bitwise and of RTEMS_PREEMPT_MASK and
+ * RTEMS_ALL_MODE_MASKS is equal to RTEMS_PREEMPT_MASK.
+ *
+ * - Check that the bitwise and of RTEMS_TIMESLICE_MASK and
+ * RTEMS_ALL_MODE_MASKS is equal to RTEMS_TIMESLICE_MASK.
+ *
+ * - Check that the bitwise and of RTEMS_INTERRUPT_MASK and
+ * RTEMS_ALL_MODE_MASKS is equal to RTEMS_INTERRUPT_MASK.
+ *
+ * - Validate the task mode mask constants except RTEMS_INTERRUPT_MASK.
+ *
+ * - Check that RTEMS_ASR_MASK is a power of two representable as an integer
+ * of type rtems_mode.
+ *
+ * - Check that RTEMS_PREEMPT_MASK is a power of two representable as an
+ * integer of type rtems_mode.
+ *
+ * - Check that RTEMS_TIMESLICE_MASK is a power of two representable as an
+ * integer of type rtems_mode.
+ *
+ * - Calculate the bitwise or of all task mode mask constants and 0xff.
+ *
+ * - Check that the count of set bits in the calculated value is equal to the
+ * count of task mode mask constants except RTEMS_INTERRUPT_MASK plus
+ * eight. Since each task mode mask constants except RTEMS_INTERRUPT_MASK
+ * is a power of two and the bitwise and of 0xff and RTEMS_INTERRUPT_MASK
+ * is equal to RTEMS_INTERRUPT_MASK this proves that each constant and 0xff
+ * has a unique value.
+ *
+ * - Calculate the bitwise or of all non-default task mode constants.
+ *
+ * - Check that the count of set bits in the calculated value is equal to the
+ * count of non-default task mode constants. Since each non-default task
+ * mode constants except is a power of this proves that each constant has a
+ * unique value.
+ *
+ * - Validate RTEMS_INTERRUPT_LEVEL().
+ *
+ * - Check the result of RTEMS_INTERRUPT_LEVEL() for a sample value.
